Office Chair Makes Loud Noise

An office chair making a loud noise may be caused by worn or loose components, uneven flooring, prolonged use, lack of lubrication, or wheel issues. Solutions include tightening components, adjusting the floor, replacing parts, adding lubricant, or cleaning the wheels.

1. Worn or Loose Components
   If the screws on the seat and backrest of the office chair are loose, or if components have naturally aged due to long-term use, it can cause creaking at the structural joints. Solution: Regularly inspect and tighten all screws, especially those connecting the seat to the backrest and the chair legs to the base, ensuring a secure installation. If components are severely aged (e.g., plastic parts are broken), replace them with new ones.

2. Uneven Flooring
   If the floor is tilted or uneven, the chair legs will experience uneven pressure, leading to wobbling and friction sounds. Solution: Place hard shims (such as rubber pads or wooden pieces) under the chair legs to adjust them until all four legs make stable contact with the floor; or replace the chair with one that has adjustable feet, allowing for fine-tuning of height to eliminate wobbling.

3. Prolonged Use
   Long-term use may lead to fatigue deformation of metal components, cracking of plastic parts, or collapse of the seat cushion, causing abnormal noises. Solution: Check the seat and backrest for cracks or deformation; if severely damaged, replace the corresponding parts. Choosing durable materials (such as thickened steel plates and high-density cushions) can extend the lifespan.

4. Lack of Lubrication
   If the metal joints of the office chair's swivel axis and lifting rod lack lubrication, friction will increase and produce noise. Solution: Use a general-purpose lubricant like WD-40 to spray the bearing joints, or use a clean cloth dipped in sewing machine oil or light mechanical lubricant to apply to the wheel axle gaps; for pneumatic lifting rods, contact the manufacturer to add special lubricating grease.

5. Wheel Issues
   Accumulated dust, foreign objects, lack of oil in the bearings, or aging of the wheels can cause a "creaking" sound or a stuck feeling when moving. Solution: Use a toothbrush or small brush to remove hair and dust from the wheel axle gaps; apply lubricant and repeatedly roll the wheels to allow the oil to penetrate; if the wheels are aged and cracked, replace them with the same model of universal wheels and ensure a secure installation.
